//
// MySqlTestBed.cs : This is base class which manages the connections to 
//                    mysql database. This serves as a base class for all
//		      mysql database dependant tests.
//
// To run :
//  * create a test database in mysql server.
//  * create an DNS entry.
//  * update the MySqlTestBed.config with the DNS names and
//    username, password for connection in the configuration key
//    MySql-DSN
//  * compile using following command
//      mcs /r:System.Data.dll,NUnit.Framework.dll /t:library /debug
//      /out:MySqlTestBed.dll MySqlTestBed.cs System.Data.Odbc/*.cs
//  * To run the tests
//      mono /usr/local/bin/nunit-console.exe MySqlTestBed.dll
